Question

A water storage tank is in the shape of a hemisphere​ (half a​ sphere). If the radius is 19 ​ft, approximate the volume of the tank in cubic feet.

Answer 1

Answer: 14,358 cubic feet

Explanation:

Volume of hemisphere = 0.5 x volume of sphere

Volume of hemisphere = 0.5 x 4/3 pi r^3

Volume of hemisphere = 0.5 x 4/3 pi 19^3

Volume of hemisphere = 0.5 x 4/3 pi 6859

Volume of hemisphere ≅ 14,358 cubic feet
